Cosmetic surgery can improve the shape, proportion, or appearance of the face and body. A person may also feel more at ease with a long-standing appearance concern after cosmetic surgery. However, every operation involves uncertainty. A careful decision about cosmetic surgery should include a clear understanding of its possible risks.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Some problems resolve with simple treatment and do not cause lasting harm. Others may require medication, hospital care, revision surgery, or long-term follow-up.
Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. During a careful consultation, patients should be able to consider the facts without being rushed. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
What Risks Can Cosmetic Surgery Involve?
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general health.
It is normal for patients to experience some minor effects after many operations. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A complication is different. A complication extends beyond normal recovery and may need medical care.
Plastic surgery complications may include the following:
- Bleeding or the development of a blood collection known as a hematoma
- Incision-site or deep-tissue infection
- Seroma formation, which involves fluid collecting beneath the tissue
- Blood clots affecting the legs or lungs
- Slow wound healing or separation of the incision
- Noticeable, raised, widened, or uneven scars
- Damage to nerves, loss of feeling, or changes in sensation
- Tissue damage or loss resulting from inadequate blood flow
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Asymmetry, contour problems, or an unwanted appearance
- Functional changes affecting breathing, movement, or feeling
- A need for further care or corrective surgery
Although serious complications are rare, they must still be reviewed before surgery. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death.
Expected Short-Term Effects of Cosmetic Surgery
Some discomfort and physical change are part of normal healing. Patients should understand what is expected so they can tell the difference between routine recovery and a warning sign.
Pain and Tenderness
Pain levels vary by procedure and patient. Tightness, aching, burning, or tenderness may occur near the surgical area. As recovery progresses, pain should generally become less intense and easier to control. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
Swelling and Bruising
Swelling is caused by inflammation and fluid moving into the treated tissues. It may hide the initial surgical result for weeks or months. Bruises form when tiny blood vessels are damaged and blood collects beneath the skin. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
Patients are advised to avoid making early judgments about their final appearance. Residual swelling can change shape, symmetry, and skin texture during recovery.
Changes in Feeling After Surgery
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Feeling frequently returns as the nerves heal, although full recovery is not certain. Permanent sensory changes are possible.
Temporary Limits on Activity
Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Patients may be temporarily unable to drive, exercise, lift heavy objects, swim, or resume their jobs. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Surgical and Medical Complications
Bleeding or Blood Collection
A small amount of bleeding may occur around an incision. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
Some hematomas can be observed, while others must be drained. Some hematomas require another operation to control the bleeding and remove collected blood.
Surgical Infection
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant smell.
Treatment may involve antibiotics, wound care, drainage, or another operation. An infected breast implant or other medical device may need to be removed. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
Postoperative Seroma
Clear fluid that gathers beneath the skin is known as a seroma. It is more common after procedures that create a large space beneath the tissue, such as tummy tuck surgery, body lift surgery, breast surgery, or extensive liposuction.
A minor fluid collection can sometimes disappear as the body reabsorbs it. Repeated drainage may be necessary when a significant seroma develops. If fluid is not treated, it may strain the incision, delay healing, or lead to infection.
Blood Clot Complications
A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. If part of the clot travels to the lungs, it can cause a pulmonary embolism. This complication can be life-threatening and must be treated urgently.
Factors that may raise blood clot risk include lengthy surgery, reduced mobility, a history of clots, particular medications, nicotine exposure, obesity, certain illnesses, and multiple procedures performed together. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable.
Poor Wound Healing
A surgical wound may take longer than expected to close or may start to open. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Treatment for a wound complication can include specialized dressings, antibiotic medication, removal of unhealthy tissue, or another operation. Healing by secondary intention means allowing an open area to close gradually from the inside outward. The recovery period may be extended, and the final scar may be more prominent.
Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues.
The extent of tissue damage determines which treatment is required. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Potential Complications of Anesthesia
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Anesthesia may be associated with the following risks:
- Postoperative nausea or vomiting
- Dizziness, confusion, or prolonged drowsiness
- A headache or irritation of the throat
- Allergic or medication reactions
- Changes in blood pressure or heart rhythm
- Breathing difficulties
- Aspiration, which occurs when material from the stomach reaches the lungs
- Damage to teeth, lips, or the airway
- Major complications involving the heart, lungs, or nervous system
Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Cosmetic Surgery Scars and Skin Changes
Any procedure that cuts the skin creates a scar. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
Scars often appear red, raised, firm, or darker during early healing. They may soften and fade over 12 months or longer. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
Hypertrophic Scars and Keloids
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. A keloid grows beyond the borders of the incision. Patients should inform their surgeon if they or close family members have developed raised or unusual scars.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Changes in Skin Colour and Texture
The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. Some of these changes resolve over time, while others can last permanently. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
Cosmetic Outcome Risks and Patient Dissatisfaction
A technically successful operation does not always produce the appearance a patient expected. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Potential cosmetic outcome concerns include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- Too little or too much correction
- A result that appears unnatural or excessively tight
- Alterations in shape while swelling resolves
- An implant that shifts, rotates, or sits incorrectly
- Noticeable scars or scars in an unfavourable location
- Recurrence of sagging or tissue laxity over time
- Dissatisfaction despite an acceptable medical result
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Anatomy and healing responses vary from one person to another.
The Possibility of Revision Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. A second procedure introduces another set of surgical risks. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. The first surgical fee may not cover a revision surgeon, facility charges, anesthesia, new implants, prescriptions, travel, or lost work time.
Procedure-Specific Cosmetic Surgery Risks
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Risks of Facelift and Neck Lift Surgery
Possible problems after a facelift or neck lift include bleeding beneath the skin, nerve damage, changes to the hairline, localized hair loss, tissue loss, uneven contours, altered earlobes, numbness, facial weakness, and noticeable scars. Nicotine use can greatly increase the risk of skin-healing problems.
Possible Rhinoplasty Complications
Rhinoplasty may cause ongoing swelling, nosebleeds, infection, asymmetry, changes in smell, visible contour irregularities, septal perforation, nasal collapse, or difficulty breathing through the nose. It can take at least a year for swelling to resolve enough for the final nasal shape to be assessed. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
Eyelid Surgery Risks
After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Possible Breast Procedure Complications
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Breast implants bring added long-term considerations. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Patients should not assume that breast implants will remain in place permanently without further care. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Tummy Tuck and Body Lift Risks
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. Activity and lifting restrictions can remain in place for a number of weeks.
Risks of Fat Transfer
Fat transfer involves removing fat from one area and injecting it into another. Because a portion of the injected fat may not survive, the final fullness and balance can change. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Who May Face Greater Cosmetic Surgery Risks?
A patient's health status and daily habits may make complications more likely. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
The likelihood of complications may increase with:
- Smoking, vaping, or using nicotine products
- Diabetes with unstable or elevated blood sugar
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity, unstable weight, or recent major weight loss or gain
- Obstructive sleep apnea
- Conditions affecting the immune system
- Inadequate nutrition or serious anemia
- Previous radiation or surgery in the treatment area
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Mental health concerns or unrealistic goals that interfere with informed decision-making
The presence of one or more risk factors does not automatically prevent cosmetic surgery. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required.
Emotional and Mental Health Considerations
The effects of cosmetic surgery may be psychological and emotional, not only physical. Some patients feel anxious, impatient, or discouraged while swollen, bruised, tired, and unable to follow their normal routine. This temporary low mood is sometimes called postoperative blues.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. Cosmetic surgery may change a physical feature, but it cannot guarantee confidence, repair a relationship, create career success, or solve broader personal problems.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. Concerns may arise when someone is being pressured, remains unhappy after repeated procedures, is intensely focused on a small flaw, or expects surgery to change every part of life.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. Surgery may not relieve the underlying concern. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
How to Reduce the Risks of Cosmetic Surgery
Although no operation can be made completely risk-free, thorough preparation can improve safety.
- Choose a properly qualified physician with training and experience relevant to the procedure.
- Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing.
- Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies.
- Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms.
- Do not compare your healing speed with edited images or another patient's recovery.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Finding a Qualified Canadian Cosmetic Surgeon
Medical regulation in Canada is handled at the provincial and territorial level. The public directory of the appropriate college of physicians and surgeons can be used to check licensing, specialty registration, and listed practice details.
Another useful question is whether the doctor holds plastic surgery certification from the Royal College of Physicians and Surgeons of Canada. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications.
Questions to ask during a cosmetic surgery consultation include:
- What training and certification do you have?
- How frequently is this specific procedure performed in your practice?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- What complications are seen most frequently with this procedure in your practice?
- Which uncommon but severe complications need to be considered?
- Who is responsible for anesthesia care during the operation?
- How can I obtain care if a problem develops at night or on a weekend?
- Where would I receive emergency care if needed?
- Which follow-up visits and services are included in the fee?
- Could I face extra surgeon, facility, anesthesia, medication, or revision fees?
What Informed Consent Should Include
Informed consent is more than signing a form. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
Patients should be informed about how the operation works, its likely benefits, material risks, alternatives, healing process, limits, and the possible consequences of no surgery. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
No one should be pushed into signing a surgical consent form quickly. When medical language or a possible complication is confusing, the patient should request a clearer explanation. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions at home.
Postoperative Warning Signs
Your surgical team should provide specific instructions about when and how to seek help. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay.
Symptoms that may require urgent care include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Sudden swelling, pain, redness, or warmth in one leg
- Uncontrolled bleeding or a sudden increase in swelling
- Severe pain that is not controlled by prescribed medication
- High fever, chills, spreading redness, or pus-like drainage
- Confusion, extreme weakness, or difficulty staying awake
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- An emergency eye symptom such as severe pain, sudden visual change, or vision loss
- Persistent vomiting that prevents normal hydration
- Any symptom the surgical team identified as an emergency
Call 911 or seek emergency care when symptoms may be life-threatening. Do not wait for an office to reopen when there is severe breathing trouble, chest pain, loss of consciousness, major bleeding, or another urgent concern.
Cosmetic Surgery Costs and Canadian Health Coverage
When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. The patient is normally responsible for surgeon fees, anesthetic services, facility charges, implants, compression garments, medication, tests, and associated costs.
Complication-related costs should be discussed before surgery. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. An inexpensive overseas package may exclude the cost of treating infection, poor healing, minimally invasive treatments DVT, implant problems, and corrective operations.
Evaluating the Advantages and Risks of Cosmetic Surgery
A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. Think about your ability to obey postoperative instructions, live with scars, take enough time off, and emotionally manage an outcome that is not ideal.
When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. Recommending against surgery can be a sign of careful and ethical medical practice.
How to Make an Informed Cosmetic Surgery Decision
Being aware of possible complications is not the same as believing they are certain to happen. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
